Abstract:

Role-based Access Control (RBAC) has become an increasingly popular access control model, particularly suitable for large organizations, and it is implemented in several software systems. Automatic security analysis of administrative RBAC systems is recognized as an important problem, as an analysis tool can help designers check whether their policies meet expected security properties. We will present Vac, an automatic tool for verifying security properties of administrative RBAC. Vac converts administrative RBAC policies to imperative programs that simulate the policies both precisely and abstractly and supports several automatic verification back-ends to analyze the resulting programs. We will describe the architecture of Vac and give an overview of the analysis techniques we have designed and implemented in our tool. We will also report on experiments with several benchmarks from the literature.
